问题 I'm using Picasso library for image downloading from the network. I just wonder whether I can use a progress dialog or a GIF image as a place holder? Also any idea on how to make place holder image to be smaller (and fit in centre) than the actual image that is downloaded? I tried going thru the samples but no luck. Any one here who got this to work? 回答1: You can use a placeholder image by using the *.placeholder(R.drawable.image_name)* in your Picasso call like: Picasso.with(context) .load
